Specification of Letters Patent.

Patented Nov. 8, 191W pplicatilmV filed October 6, 1909. Serial No.521,190.

To all whom it may concern:

Be it known that I, PAUL L; BOUSQUET, a citizen of the United States,residing at Akron, in the county of Summit and State of Ohio, haveinvented new and useful Improvements in Fabrics, of whichthe follow'-ing is a specification.

This invention relates to improvements in fabric especially adapted tobe used in the manufacture of rubber articles such as pneumatic tiresand gaskets.

The object of this invention is to provide an improved fabric especiallyadapted for use in the manufacture of outer shoes of pneumatic vehicletires so constructed as to possess great inherent strength for thepurpose of preventing puncture and blow-outs in the tire casing; andalso adapted to other uses where fabric having great strength isrequired.

The invention contemplates forming a fabric, either by weaving orotherwise, from threads each of which embodies a central metallic wireor core around which are wrapped a plurality of strands of fibrousmaterial, previously impregnated with a solution of a vulcanizable gumcompound, preferably capable of being dried previous to the wrapping ortwisting of the strands about the metallic wire or core'. After themanufacture of these threads the fabric is constructed in any preferredmanner therefrom. With the foregoing and other objects in view, theinvention consists in the novel construction, combination andarrangements of parts constituting the invention to `be hereinafterspecifically described and illustrated in the drawings which form a parthereof wherein is shown the preferred embodiment of the invention, butit is to be understood that Ichanges, variations and modifications canberesorted to which come within the scope of the claim hereuntoappended.

in the drawings, in which similar reference numerals indicate like partsin the different figures: Figure 1 is a view' of a thread used inconstructing a fabric embodying' this invention; and, Fig. 2 is a viewof a piece of woven fabric employed to illustrate one Way of utilizingthe threads shown in Fig. 1.

' It is believed that the invention will be better understood by givinga brief description of the process by which the fabric is manufactured.The threads from which the fabric is made is constructed by wrapping ortwisting about a central core or a line wire 1 a plurality of strands 2of a fibrous material such as long-fiber Sea-island cotton the strandsof which have preferably been dipped or immersed in a bath of a solutionof a vulcanizable gum compound, such for instance as rubber cement,after which the strands impregnated with the vulcanizable rubbercompound are permitted to dry and are then preferably wrapped or twistedby machinery about the wire or core 1, as shown in Fig. 1, after whichthe threads are formed into fabric, either of coarse or fine mesh, asdesired, the piece of vfabric shown in the drawings having an unusuallylarge mesh to better illustrate the construction of a woven fabric madefrom threads constructed in accordance with this invention. s v

If the fabric is employed in the construc- 'tion of articles which areafterward to be vulcanized, the vulcanizable gum with which vthe strandsare impregnated is also simultaneously vulcanized with the article. Thecommon mode of constructing rubbersaturated fabric is to impregnate thesame as far` as possible with a vulcanizable gum compound, after thefabric has been Woven, and as the strands composing each of the threadsor .yarn from which the fabric is made are ordinarily twisted, thevulcanizable gum compound does not penetrate and impregnate the threadsto such an extent as to render the product as satisfactory as it is inthe present-invention wherein each o f the threads, previous to itsbeing wrapped or twisted about the central core ory Wire, 1s rstimpregnated. The thread constructed from these strands is saturated withthe solution of vulcanizable gum compound to such an extent that whenvulcanized all portions of the thread and-consequently 'all portions ofthe fabric are eifectually and completely cured by the vulcanizingprocess.

As each thread in the fabric is composed ofa central core or wire bothadditional strenuth and durabilitv are imparted to the fabric, whichcould not be obtained where threads of fibrous material are used alone;but in this invention where the strands are wrapped abouta metalliclcore these desidcanizable gum compound, serves to protect the Wireagainst the deleterious action of the elements. From this it Will beseen that a fabric made in accordance With this invention provides ahighly desirable product for use in making the outer shoes or casings ofdouble-tube pneumatic tires wherein great pliability alid strength arerequired, to furnish to t-he vehicle on which the tire is used,

elasticity of a tire provided with 'this kind,

of fabric, and the ordinary accidents of puncture and blowing out arereduced to' a minimum, the life of the tire being thus prolonged.

What I claim and desire to secure by Letters Patent, is

A fabric for the purpose described comprising Warp and weft threadswoven together, each of said threads embodying a Wire constituting acore inclosed by a plurality of strands of fibrous material, each ofsaid strands having been impregnated with a solution of a vulcanizablegum compound previous to its-superimposition on said Wire, whereby allportions of the fabric covering each of said Wires is saturated withsaid vulcanizable compound, so that When said fabric is subjected to avulcanizing heat the fibrous covering will be intimately united togetherand to said Warp and weft threads to 4constitute a flexible unitary andapproximately Water-proof structure In testimony whereof I have hereuntoset my hand in presence of two subscribing witnesses.
